The average monthly income of certain agricultural workers is S and that of other workers is T . If the number of agricultural workers is 11 times that of other workers, then the average monthly income of all the workers combined is:

Solution & Step-by-step Explanation

Let the number of other workers be x . Then, the number of agricultural workers is 11 x . Total number of all workers = 11 x + x = 12 x . * Total income of agricultural workers = 11 x \times S = 11 x S * Total income of other workers = x \times T = x T * Total income of all combined workers = 11 x S + x T = x (11 S + T) Combined weighted average = \frac{Total Income}{Total Workers} Average = \frac{x ( 11 S + T )}{12 x} = \frac{11 S + T}{12}

Try it yourself before checking the explanation above.

The average monthly income of certain agricultural workers is S and that of other workers is T . If the number of agricultural workers is 11 times that of other workers, then the average monthly income of all the workers combined is:

\frac{S + T}{2}

\frac{11 S + T}{11 + 1}

\frac{S + 11 T}{12}

\frac{11 S + T}{12}
